Plant regeneration through somatic embryogenesis in Quercus suber

open access: yesPhysiologia Plantarum, 1992
Cork oak (Quercus suber L.) zygotic embryos, endosperm and ovules were treated with different concentrations of 2,4‐D for induction of somatic embryos. Plant material was collected during the embryo development season, from June to September. Immature embryos proved to be the most reactive initial explant.

Hermit beetle (Osmoderma barnabita) habitat selection and movement are shaped by tree microhabitat availability in Eastern Romanian Carpathians

open access: yesInsect Conservation and Diversity, EarlyView.
We conducted the first radio‐tracking study on Osmoderma barnabita to examine the movement ecology and habitat selection in the Eastern Carpathians. A female recorded the longest movement distance and had larger home ranges than males. It showed a preference for Quercus petraea, with wood mould cavities and DBH as key predictors.

RNA-Seq and gene network analysis uncover activation of an ABA-dependent signalosome during the cork oak root response to drought

open access: yesFrontiers in Plant Science, 2016
Quercus suber (cork oak) is a West Mediterranean species of key economic interest, being extensively explored for its ability to generate cork. Like other Mediterranean plants, Q.

Somatic Embryogenesis of Quercus suber L. From Immature Zygotic Embryos [PDF]

open access: yes, 2018
Quercus suber L., cork oak, is a forest tree of high social and economic value. The cork is traditionally used in the wine industry to produce bottle stoppers, but it is also a very good material for both thermal and acoustic insulation in construction.

Sheep and cattle grazing regimes differentially affect ground beetle and ant communities in Mediterranean cork oak woodlands

open access: yesInsect Conservation and Diversity, EarlyView.
Sheep and cattle grazing significantly shape ant and ground beetle species composition in Mediterranean cork oak woodlands, promoting higher diversity by increasing habitat heterogeneity. Ground beetles and ants reflect changes in grazing regimes, with sheep‐grazed areas showing the highest diversity, highlighting their utility in ecosystem monitoring.

Quantitative RT-PCR analysis of differentially expressed genes in Quercus suber in response to Phytophthora cinnamomi infection [PDF]

open access: yes, 2014
cDNA-AFLP methodology was used to gain insight into gene fragments differentially present in the mRNA profiles of Quercus suber roots infected with zoospores of Phytophthora cinnamomi at different post challenge time points.

Heat treatment duration affects in vitro‐induced photosynthetic impairment and development of necrotic leaf tissue in three Mediterranean oak species

open access: yesPlant Biology, EarlyView.
Longer lasting heat treatment durations induced photosynthetic impairment at lower temperatures and caused the development of proportionally more necrotic tissue at lower temperatures in leaves of three Mediterranean oak species. Abstract Short heat treatments are commonly used to estimate the leaf‐level thermal tolerance of tree species. The effect of
